This flavorful tater tot casserole is easy to prepare and cook in the slow cooker or in the oven. Use frozen mixed vegetables or a blend of peas and carrots, and saute 1 cup of chopped onion with the ground beef if you like.


  • 1 pound ground beef
  • 1 (32 oz.) bag tater tots 
  • 1 (about 16 oz.) bag frozen mixed vegetables (cooked)
  • 2 cans (10 3/4 oz. each) of cream soup (mushroom or celery, take your pick)*

Steps to Make It

  1. Gather the ingredients.

  2. Put the ground beef in a large skillet over medium heat. Cook, stirring and breaking up until the beef is no longer pink.

  3. Mix the browned ground beef with 1/2 bag of tater tots, cooked veggies, and soup.

  4. Spoon into a buttered slow cooker insert.

  5. Layer the remaining tater tots on top.

  6. Cook on low for 5 to 7 hours—or about 3 hours on high.

Oven Method

Alternatively to a slow cooker, the casserole can be made in an oven. Pre-heat oven to 350 F. Butter or grease a baking dish. Prepare the ingredients as instructed above, pour the prepared ingredients into the dish and top with layer of reserved tater tots. Cover the pan with foil and bake in the pre heated oven for about 50 to 60 minutes. Then remove foil and continue cooking for 10 to 15 minutes until tots are browned.


  • Use extra condensed soup if the casserole seems very dry.
